<title>About Configuration Parameters</title>
|
|
<para>&PRODUCT; provides a variety of settings you can use to set limits, configure features,
|
|
and enable or disable features in the cloud. Once your Management Server is running, you might
|
|
need to set some of these configuration parameters, depending on what optional features you
|
|
are setting up. You can set default values at the global level, which will be in effect
|
|
throughout the cloud unless you override them at a lower level. You can make local settings,
|
|
which will override the global configuration parameter values, at the level of an account,
|
|
zone, cluster, or primary storage.</para>
|
|
<para>The documentation for each &PRODUCT; feature should direct you to the names of the
|
|
applicable parameters. The following table shows a few of the more useful parameters.</para>

<entry><para>A CIDR that describes the network that the management CIDRs reside on. This

variable must be set for deployments that use vSphere. It is recommended to be set
|
|
for other deployments as well. Example: 192.168.3.0/24.</para></entry>

<entry><para>For XenServer nodes, this is a true/false variable that instructs
|
|
CloudStack to enable iSCSI multipath on the XenServer Hosts when they are added.
|
|
This defaults to false. Set it to true if you would like CloudStack to enable
|
|
multipath.</para>
|
|
<para>If this is true for a NFS-based deployment multipath will still be enabled on

the XenServer host. However, this does not impact NFS operation and is

harmless.</para></entry>

<entry><para>This is used to protect your internal network from rogue attempts to
|
|
download arbitrary files using the template download feature. This is a
|
|
comma-separated list of CIDRs. If a requested URL matches any of these CIDRs the
|
|
Secondary Storage VM will use the private network interface to fetch the URL. Other
|
|
URLs will go through the public interface. We suggest you set this to 1 or 2
|
|
hardened internal machines where you keep your templates. For example, set it to
|

192.168.1.66/32.</para></entry>

for data disks, templates, and snapshots. By default CloudStack will not use this
|

storage. You should change this to true if you want to use local storage and you

understand the reliability and feature drawbacks to choosing local

storage.</para></entry>

command. The limit applies at the cloud level and can vary from cloud to cloud. You
|
|
can override this with a lower value on a particular API call by using the page and

page size API command parameters. For more information, see the Developer's Guide.

as dedicated HA hosts. These hosts will be used only for HA-enabled VMs that are
|
|
restarting due to the failure of another host. For example, you could set this to
